Vivek Agnihotri, the Bollywood director, has announced a film on how Prime Minister Lal Bahadur Shastri must have died on 11 January 1966.

Titled 'The Tashkent Files', the movie will be made as an investigative thriller. "On 10th Jan 1966, in Tashkent, a tiny man called Lal Bahadur Shashtri who won a war with Pakistan, soon after a humiliating defeat with China, signed the Tashkent treaty. Hours later he died. A death mystery unsolved till date. Why?" Vivek questions.

"On this day, our 2nd PM Lal Bahadur Shashtri died mysteriously in Tashkent. Was it heart attack or poison? Even after 52 yrs, the truth of the biggest cover-up of free India has been denied to his family, followers, citizens. After years of research, I present #TheTashkentFiles," he goes on to say.

Who will play Lal Bahadur is not known as yet. Naseeruddin Shah and Mithun Chakraborty have been roped in for other roles.
